METAL-BINDING MACHINE.

Application filed ui 11, 1924. Serial no. 725,464.

To all whom it may concern:

Be it known that I, MURRAY A. WAoHs, a citizen of the United States, and resident of the city of New York, borough of Brooklyn. in the county of Kings and State of New York, have invented a new and Improved Metal-Binding Machine, of which the following is a full, clear, and exact description.

This invention ing machines and refers more particularly to a machine for attaching metallic binding elements to the corners or edges of articles such as pocketbooks or the like, the same being in the nature of. an improvement of my co-pendin a and bearing er1al Number 711,404.

Broadly this invention comprehends an improvement in a machine of this character for attaching or affixing binding elements particularly of an ornamental nature to the corners or edges of articles suchas pocketbooks or the like.

One of the outstanding objects of the present invention is to provide an improved machine of this nature, in which means is provided for flushing the bight of the binding element withthe edges of the article or material to which it is applied whereby to eliminate the projection or extension of the binding element beyond the edge of the article.

As a further object the invention contemplates in connection with a machine of the character set forth means for controlling or regulating the flushing means to compensate for variations in the thickness of the material from which the bight is formed.

As a still further object the invention contemplates a means for compensatin for the thickness of the ad acent being applied thereto, in order to e ualize the pressure of the binding member uring the binding operation and to insure an even gripping of the same throughout.

The invention furthermore contemplates a means for ,adjustably limiting'the movement of the binding element whereby the same may be set for use in connection with binding elements or clips and articles to which they are applied in which the combined thickness thereof varies.

Other objects of the invention reside in the revision of a machine of the character set orth which is cQmparatively simple in has relation to metal bind lication filed May 6, 1924,

fication, particularly pointed out in the appended claims and illustrated in the accompanyrng drawmgs, it being understood that the rightis reserved, to embodiments other than those actually illustrated herein, to the full extent indicated by the general meaning of the terms in-which the claims are expressed.

on the line 33 on Fig, 2 and illustrating the manner in which the Referring to the drawings by characters of reference the machine includes a base 10, an upstanding arm 11 at one end of the base having a horizontal overhanging end 12 provided with an upwardly projecting bifurcated terminal 13 the furcatio-ns lehof which are provided with aligned apertures 15 to receive therebetwcen the apertured end. of an operating lever 16 which is fulcrumed thereto by a transverse pivot pin 17. The horizontal overhanging portion 12 of the arm 11 of the machine is provided with a vertical bearing opening through which a plunger rod 18 extends and is vertically movable. The plunger rod has secured thereto a collar 19 at the portion of the rod which extends below the horizontal portion 12 of the arm and which is designed to coact with the underside of-the portion 12 to limit the upward vertical movement thereof. Adjacent its upper end, the plunger rod 18 is provided with a suitable element in the nature of a transverse pin 20 between which and the upper side of the portion 12 a coiled expansion spring 21 is interposed for normally elevating the plunger rod to the limit of itsupward movement. The upper terminal of the plunger rod 18 is ofsemispherical formation as illustrated at 22 and is designed to tit in an arcuate recess 23 on the under side of the lever 16. Under. this arrangement it will be observed that downward swinging movement of the lever 16 either by hand or foot power will effect a downward movement of the plunger rod against the action of the spring 21. A head 2 1is secured to the lower end of the plunger rod for movement therewith and said head is provided with an upwardly projecting guide rod 25 extending through a vertical guide opening 26 in the horizontal overhanging portion 12 of the machine arm, whereby to prevent rotary movement of the head and plunger rod and guide the same in a vertical path of movement only. At its forward end the head 24 is provided with a binding or pressure foot 27 which in the present instance includes forwardly and outwardly divergent wings 28 defining a V-shaped recess at the forwardend of the head. In order to provide means for positively holding the pocketbook or other article to which the binding elements are to be applied,- in immovable relation to the base, a holding member 29 is employed which is provided with complementary divergent outer faces 30 which are snugly received within the V-shaped notch defined by the wings 28.'

The holding member 29 is provided with a stem 31 which extcndsupwardly through the aligned apertures 32 and 33 formed respectively in the radial arm 34 of the collar 19 and in the overhanging portion 12 of the machinearm 11. A stop pin 35 extends nuances transversely through the stem 31 above the radial arm 34: for the purpose of limiting the downward movement of the holding member 29 relative to the head 24; and binding member 28. A coiled expansion spring 36 surrounds the stem and is interposed between the member 29 and the radial arm 34 for normally projecting the member downwardly and yie'ldably maintaining the member 29 in a downwardly spaced relation from the radial arm 34-, with the stop pin 35 in engagement with said arm.

The flushing means consists of a horizontally disposed. plate 10 which is arranged for forward and rearward sliding movement in flat contact with the upper face the base 10, the same being formed at its rear end with a cross bar 41 having rearwardly projecting guide stems 4.2 which extend through horizontal guide openings 43 in the machine arm 11. The rear arms of the guide stems 42 project beyond the rear side of the machine arm 11 and are provided with suitable pins tat extending transversely therethrough, between which in the'rear face of the arms coiled expansion springs 45ers interposed for normally retracting the plate 10 or moving the same rearwardly whereby its rear end provided with the crossbar 41 is impinged against theforward" lower portion of the machine arm 11. The medial portion of the cross-bar 4'1 is provided with a rear recess .46 having an upwardly and forwardly inclined cam face 47. The rear end of the head 24 is provided with a rearwardly projecting tail 18 which ex tends over the cross-bar 41 and a vertically adjustable cam pin 49 depends from the tail 48 for engaging the cam face 47. The cam pin is preferably threaded throughout the major portion of its length as at 50 and is provided with a 'kerf 51 at its upper end whereby a screwdriver may be engaged therewith for effecting vertical adjustments thereof. A binding nut 52 is threaded over i the upper end of the cam pin for locking the same in its vertically adjusted position.

In order to provide means for facilitating the proper positioning of the article with respect to the holding member 20, gage elements 55 are employed which consist of slotted bases 56 "arranged in flat contact with the upper surface of the machine base 10, said bases having, retaining screws 57 extending through the slots thereof and an-- chored in the base 10. At one end the base is provided with an upstanding gage flange 58 against which the edges of they article are adapted to abut. In order to provide means for gripping and maintaining'the article in abutting relation to the gaged flanges 58, leaf-springs 59 are employed which are anchored as at 60 at the upper face of the base and are provided at their free end with upwardly curved terminals 61,

The article A as illustrated in 3, 6 and 8 to which the binding clip or element B is to be appliedand attached initially has the element B arranged in juncture position thereon. Thebinding elements or clips B as particularly illustrated in Fig. 2 are of substantially U-shape in cross-section and the purpose of bending the opened up portions downwardly whereby the flanges D and E ot the binding element or clips when applied will be, disposed in parallel relation to embrace the opposite faces of the article A with the bight C in bracing the edge of said article. The machine further functions to embed the-anchoring means or spurs F in the article A to lock the binding elements or clips in place thereon.

In use and operation of the machine the gage elements are properly'set; the operatorthen positions the article A with the applied clip or binding element B on the-upper surface of the base or bed 10 of the machine whereby the edges of the article abut the gage flanges 58 and the leaf springs cramp the article initially in place. The operator then by exerting a downward pressure on the lever 16 moves the plunger rod 18 and its head 24 downwardly which initially effects the impingement of the holding member 29 into engagement with the article due a to the fact that the lower edge of the holding member 29 is normally projected below the lower, edge of the binding member 28 by. thespring 8 6. The holding member 29 thus further grips and maintains the article with its applied clip in immovable relation to the base or bed 10. Further continued downward pressure on the. lever 16 effects a further downward movement of the plunger rod 18 and the head 24. The next operation consists of a forward movement of the flushing plate 40 which due to the interengagement of the cam pin 49 with the cam face 47 of the cross-bar 41 is advanced forwardly to force the bight C of the clip or binding element until the bight is flush with the edges of the article. Immediately following a completion of the flushing operation a further continued downward movement of the head' 24 brings the binding or pressure foot 27 into engagement with the, opened up portions of the clip or binding element to bend the same downwardly and embed and anchor the spurs F in the article A. i

k I I i i In order to prevent crushing of the binding element or clip by limiting the final downward movement of the head and pressure foot, :1 stock member is employed which may consist of a pin threadedly engaged in a socket in the overhanging portion 12 of the machine arm, with which the underside of the lever 16 is adapted to engage. The stop member 65 is vertically adjustable in order to regulate the limitation of the dowir ward movement of the lever 16, plunger rod 18 and plunger head 24 whereby the machine may be adjusted to compensate for various combined thicknesses in V the binding elements or clips and the articles to which they are applied.

In many instances where corner clips or binding elements'are applied, one of: the adjacent edges of the article is of lesser thickness than the other, and in order to provide means for compensating thereforto equalize the pressure of the pressureorbinding foot 27, shim arms 66 are provided at the extremity of pivoted levers 68 which are fulcrumed on vertical pins 69 anchored in the upper face or bed 10. The levers 68 in addition to being mounted on the pin for turning movement are mounted thereon for rocking movement" vertically by interposing between the'underside'of the lever and the 1 upper surface of the base a coiled expansion spring '(0 and by 1.nterp0singhetwecn the upper side of the lever and transverse stop pins 1 coiled expansion springs 7 2. The springs 72 have one of the end convolutions hooked over the edge of the lever68 as at 73 with the opposite end convolution suitably attached to the pin whereby the lever is normally swung to a position to throw the shim arm 66 to an out of the way position. Vhen it is desired to use the shim arm the lever is swung on its pivot to dispose the same in the position illustrated in dotted linesin Fig. 4. This position is obtained by engagement of the lever with the stop pin 7 4 whereby the shim arm directly overlies .and

is disposed in the path of movement of the pressure or binding foot 27. 'hen the lever 68 is released it will be noted that the spring 72 turns the same on its pivot until the free end of the lever is arrested from further movement by engagement with the gage flanges 58 of the gage elenients 55,

After the attaching or afiixing operation is completed, the release of pressure on the lever 16 permits the plunger spring 21 to return the lever, plunger rod. plunger head 24, pressure foot 27 and holding member 29 to normal position while the disengagement of the cam pin 49 in the cam face 47 permits the springs 45 to react the flushing plate 40. i

\Vhile the form of machine illustrated is particularly designed for the application of corner clips, it is of couise to be understood I that the scope of the claims is such as to.
